Acclamation was formerly one of the methods of papal election.

The method of electing the Roman Pontiff is contained in the constitutions of Gregory XV Æterni Patris Filius and Decet Romanum Pontificem, Urban VIII's constitution Ad Romani Pontificis Providentiam, and John Paul II's Universi Dominici gregis, issued in 1996. Prior to the issuance of Universi Dominici gregis, three methods of election were valid. These were by scrutiny, by compromise, and by acclamation (or "quasi-inspiration"). This last form of election consisted of all the electors present unanimously proclaiming one of the candidates Supreme Pontiff, without the formality of casting votes. As this was required to be done without previous consultation or negotiation, it was looked upon as proceeding from the Holy Spirit and hence was also designated "quasi-inspiration".
